People logging in to office computers, people logging in to lab computers, people accessing files on file servers, people printing to printers on print servers

Affected in what way:

You may have intermittent problems accessing files not saved on your computer (on a file share or server* or Sharepoint) or printing to printers (on a print server**) on Friday, November 26th. You should have no problem logging into office computers that you use regularly; however, you could see a short delay.
People logging into labs will be unable to login if both servers are unavailable.
*File servers usually show up in My Computer with a drive letter that is later in the alphabet (U:, S:, etc.) or have a \\ in the name. They may also say "Network drive" in their description when you click on them.
**Printers on print servers usually have the word "on" in the name, for example "dell5100 on hsu-print" or you may see a \\ in the name.

Workaround:

If there are files that you must be able to access on 11/26, you may want to save them to your computer ahead of time.
If you are unable to access a resource or login, wait a few minutes and try again.

What happened:

ITS will be upgrading the two servers that allow you to login to computer systems on campus (Active Directory). We expect logins to work throughout the entire day; however, there may be short outages that prevent you from logging in or connecting to a networked-based resource (file server or print server).
